P. 214-220Matter & Temperature Study Questions: Can you answer these? Did you write these in your notes?
States of Matter • What property of matter is affected by temperature? • What state of matter is water in when it is at a low temperature?
Solids • Describe the kinetic theory of matter. • Why can’t solids be squeezed into smaller spaces? • Explain why solids cannot change shape. • What type of substances can appear solid even though they really are not?
Liquids • What characteristics of liquid particles explains why liquids cannot be squeezed into smaller volumes? • What characteristic explains why liquids take on the shape of their container? • Describe how liquid particles are both similar to and different from solids.
Gases • What two characteristics of gases allow them to be described as “springy”? • Compare the spacing of gas particles to those in liquids and solids.
More on Gases • What characteristic of gas particles allow them to spread and fill their container? • What characteristic allows them to be compressed into smaller spaces? • Compare the properties of solids, liquids and gases.
Plasma • Where is plasma most abundant? • Describe how plasma is different from gas.
Thermal Expansion • What is an expansion joint? • Why do concrete structures have gaps built into them? • What is thermal expansion?
Thermal Expansion • Describe how particles in a solid change when heated. • Explain what causes solids to expand when heated. • Explain why the liquid in thermometers moves up the tube when heated.
